How to Use Google for Calendars But Yahoo! for Mail, Contacts on iPhone

My post last week about merging Google Contacts generated a related question from Dave Zatz, because although he’s very content with Yahoo! (s yhoo)for mail and contacts, he’s interested in using Google Calendar (s goog) for events on his iPhone (s aapl). Surely you can’t mix and match among these on a single device, right? Actually, it turns out that you can do this thanks to the magic of Google Sync.

Xsigo Raises Money for Virtual I/O

Stack_Comparison_HorizXsigo today said it’s raised an undisclosed amount of venture capital from Kleiner Perkins Caufield & Byers, Greylock Partners, Khosla Ventures and North Bridge Venture Partners to support sales of its I/O virtualization appliance. Several filings submitted to the California Department of Securities show that back in April, the San Jose, Calif.-based startup had raised as much as $51 million, but Jon Toor, VP of marketing for Xsigo, declined to comment on either amount. Xsigo’s appliance sits inside a rack of virtualized servers and manages the way the virtual machines on those servers talk to one another, the network and the storage infrastructure. The Xsigo appliance works with any hypervisor, network and storage type. Read More about Xsigo Raises Money for Virtual I/O

Next Up: I/O Virtualization?

Austin, Texas-based startup NextIO has scored $18.8 million in a third round of funding, bringing the I/O virtualization systems maker to almost $40 million in total venture capital raised since 2003. It’s attacking one of those nitty-gritty technical problems in data centers and tossing around today’s favorite buzzword to do it.

NextIO makes chips and software to tackle I/O virtualization for the PCI Express protocol. Virtualized I/O allows a group of servers and/or storage systems to run Ethernet, FibreChannel, InfiniBand or whatever other flavor of interconnect technology through one box. This makes it easier to manage a network without having to map each server to a set endpoint. NextIO expects to ship products this year to OEMs that make servers and storage systems.

It’s not alone in attacking aspects of I/O virtualization. Others include Neterion, NetXen, 3Leaf, Xsigo and even some 10Gig-E players who have added I/O virtualization capabilities such as Solarflare Communications are trying to bring virtualization across the data center.
